70% to passIf the compensating needle valve of a hydraulic governor is opened more than necessary the governor will_______________.
Aproduce excessive speed response to a load change
Bstabilize engine speed at the new governor setting
Chave a larger than normal deadband
Drespond slowly to any change in engine load
AI Explanation
The correct answer is A) produce excessive speed response to a load change. When the compensating needle valve of a hydraulic governor is opened more than necessary, it reduces the damping of the governor's response to load changes. This causes the governor to overreact to load changes, resulting in an excessive speed response as the engine speed fluctuates excessively rather than stabilizing at the new governor setting. The other options are incorrect because opening the compensating needle valve more than necessary does not stabilize the engine speed, increase the deadband, or slow down the governor's response to load changes.
